It's unrealistic that someone would write a GUI interface in response to an active computer attack. The reference: https://youtu.be/hkDD03yeLnU
The GUI isn't "written", it's drag and drop. You add functionality as needed to the GUI events, like the code you would have put into a console program goes into a button's OnClick event instead.
It's probably faster than writing a console program for anyone who isn't a developer.
